The two-section wooden enclosure (10) has a first section (40) including a top panel (18) secured to a plurality of mounting brackets (42A, 42B), and a second section (60) including a front panel (20) having a first side panel (22) and a second side panel (26) secured to opposed side ends (24, 28) of the front panel (20). The first section (40) is secured to a hydropic finned tube heater (59) and a vertical wall (12). The first and second side panels (22, 26) of the second section (60) are secured to the vertical wall (12) so that the front panel (20) is adjacent and below the top panel (18) to cover the finned tube heater (59). The second section (60) may be removed from the vertical wall (12) without removal of the first section (40) from the vertical wall (12).

A ceiling-embedded air conditioner includes a decorative panel, a turbo fan, a heat exchanger, a drain pan, an air suction path, air blowoff paths provided at four places along the sides of a virtual square surrounding the air suction path, and an air blowoff opening communicating with the air blowoff path. The air blowoff path is formed in a cuboidal shape having a pair of long side walls disposed with a predetermined space therebetween in parallel to the sides of the virtual square and a pair of short side walls connecting the ends of the long side walls. Airflow guide vanes are provided in the air blowoff paths to direct part of blown airflow toward the short side of the air blowoff opening.

A ceiling-embedded air conditioner includes: a decorative panel; a turbo fan; a heat exchanger; an air suction path; air blowoff paths; an air suction opening and air blowoff openings that are provided in the decorative panel; corner panels disposed at corner portions between the adjacent air blowoff openings; a human sensor that is provided on a specific corner panel; a wind guide path that flows conditioned air blown from the air blowoff openings; and windbreak ribs that are erected from the specific corner panel to suppress direct strike, on the human sensor, of the conditioned air flowing from the wind guide path to the specific corner panel.

An explosion-protected housing, such as a switchboard, junction box, distribution box, or the like, comprising sidewalls, one back or bottom wall connecting the sidewalls, and a lid or door wall part closing a housing opening. In the housing interior, electronic and/or electric components are arranged, wherein the housing comprises a cooling device. To allow the cooling of a plurality of electronic and/or electric components in the housing interior in a simple way and without higher costs and requiring more space, at least one cooling pipe as a cooling device is provided in at least one wall or a wall part and is closed to the housing interior and flowed through by a cooling fluid.

A ceiling-embedded air conditioner includes: a decorative panel; a turbo fan; a heat exchanger; a drain pan including a drain sheet; an air suction path; cuboidal air blowoff paths that are provided at four places surrounding the air suction path; and rectangular air blowoff openings that are provided in the decorative panel. The air blowoff paths are integrated with the drain pan. Airflow guide vanes are provided in the air blowoff paths to direct part of the blown airflow toward the short side of the air blowoff opening. Attachment portions formed of the same material as that for the drain sheet and configured to attach the airflow guide vanes are provided at an inflow-side opening portions of the air blowoff paths.

A heat exchange device includes a housing, a heat exchange module, and a piezoelectric module. Isolated inner and outer circulation chambers are formed in the housing. The heat exchange module in the housing includes a stack of separated plates parallel to each other. An inner channel communicated with the inner circulation chamber and an outer channel communicated with the outer circulation chamber are defined respectively by both sides of one of the plates and the other adjacent plates. The piezoelectric module in the housing includes a piezoelectric chip, and first and second heat exchange sides thermally coupled to the piezoelectric chip. The first heat exchange side is located in the inner circulation chamber and the second heat exchange side is located in the outer circulation chamber, so that heat can be transferred between the inner and outer circulation chambers via the piezoelectric chip.

A deployable kitchen includes an enclosure, an appliance within the enclosure, and a recapture plenum. The appliance includes a housing and a burner unit that is within the housing. The appliance defines cooling passage between the housing and the burner unit. The cooling passage is in thermal communication with the burner unit such that an airflow through the cooling passage establishes an air buffer between the burner unit and the housing. The housing includes a face that defines an outlet of the cooling passage. The recapture plenum encloses the face of the housing such that the recapture plenum receives an exhaust portion of the airflow after the airflow is conveyed through the cooling passage. The recapture plenum is configured to be in fluid communication with a heating vent within the deployable kitchen.

A ceiling-embedded air conditioner includes: a pipe draw portion that is provided at one corner portion of a casing main body to draw refrigerant pipes together with an electric wire; a pipe cover that fixes the peripheries of the refrigerant pipes and has a draw hole for the electric wire; a wire cover that is provided on the bottom surface of the casing main body and cover a wire guide groove for the electric wire; a cover plate that is included in the wire cover, covers the wire guide groove, and is screwed to a predetermined place on the casing main body side; and a hold plate that is included in the wire cover and is folded at a right angle from one end of the cover plate to engage with a pipe cover end portion of the pipe cover on the bottom surface side of the casing main body.

A ceiling-embedded air conditioner includes: a main unit; a decorative panel having an outer frame portion, an inner frame portion disposed more inside than the outer frame portion, and connection portions connecting the outer frame portion and the inner frame portion at corner portions; a blowoff path disposed between the outer frame portion and the inner frame portion; blowoff openings formed between the adjacent connection portions in the blowoff path; and wind direction plates covering the blowoff path. The wind direction plates include shaft portions. Plate-like bearing support columns are erected from the connection portions. The bearing support columns include at the tips shaft holes for supporting pivotally the shaft portions and include ventilation holes between the shaft holes and the connection portions.
